Thanks, but can you explain question 21 for me like why you have to do 50×200÷5 and Question 9 where do you get Q3 and Q1 from, do you use the line? because im trying to cut this graph it quarters and i cant do it :SQuestion 9:
Q3-Q1= 65.5-35.5=30
The IQR is the difference between Q3 and Q1
Q1 and Q3 is determined by the 1/4 and the 3/4 point in the data. Just as a side note Q2 is 55.5
Question 13:
You need this formula: yield=dividend/(market price)×100% (I don't think the formula sheet includes it, so you need to memorise it)
Question 21:
Total= 50×200÷5=2,000
Ohh I get it. Thanks heapsFor Q 17
in three extra students go C=2(n+3) + 5 as n is the number of students already going
C=2n+11 so the chose increases by 11-5 = 6 =A
